-
RESELLER but publisher
1,032 lines
If the account is yours, declare it DIRECT. If a partner holds it, ask mars.media why the account is listed as PUBLISHER.
-
Seller ID not found
47 lines
Ask mars.media for the account ID it lists for you in its sellers.json, correct the line, or remove it if you no longer work with them. Buyers that check sellers.json drop these paths.
-
Seller type BOTH
17 lines
The account is listed as BOTH, so sellers.json alone cannot tell a buyer which relationship applies. Nothing to fix on your side; buyers usually look at the seller's domain.

Questions about mars.media
How do I add mars.media to app-ads.txt?
Add one line for each account mars.media gives you: "mars.media, YOUR_ACCOUNT_ID, DIRECT, 8624339f102fb076". Use DIRECT when you hold the account yourself and RESELLER when a partner holds it and sells your inventory through mars.media. The account ID must be the seller_id mars.media lists for you in its sellers.json; mars.media will give it to you. Put the file at the root of the domain named as your developer website in the App Store and Google Play listings.
Does mars.media publish a sellers.json?
Yes. Its file at https://mars.media/sellers.json listed 401 sellers when we last read it on 9 October 2026: 328 publishers, 43 intermediaries and 30 listed as both; 0% are confidential.
How many apps declare mars.media in app-ads.txt?
125,811 apps in Stoqlab's data (delisted apps included) declare mars.media: 25,325 with at least one DIRECT line and 125,259 with at least one RESELLER line, across 16,517 app-ads.txt files. Counts are recomputed daily.
What is the certification authority ID for mars.media?
76% of the app-ads.txt lines naming mars.media carry "8624339f102fb076" in the fourth field. The field is optional; the IAB Tech Lab ads.txt 1.1 specification says identifiers in sellers.json supersede it, so a missing or different value does not make a line invalid.
Why do mars.media lines fail verification?
Of 81,663 lines naming mars.media, 2,658 contradict its sellers.json. The most common case is "DIRECT but intermediary" (1,579 lines): If a partner holds this account and resells your inventory, the line should say RESELLER. If the account is yours, ask mars.media to list it as PUBLISHER.
What is the difference between DIRECT and RESELLER?
DIRECT means the publisher owns the account; RESELLER means an intermediary sells the inventory on the publisher's behalf. DIRECT lines should match a PUBLISHER entry in the network's sellers.json, RESELLER lines an INTERMEDIARY entry.
